Engine Replacement Guide

If replacing a Briggs & Stratton engine with a Briggs & Stratton engine, provide the original engine’s model andtype numbers to assure the correct replacement. If replacing a competitor’s engine with a Briggs & Stratton engine, let the horsepower and features of the original engine plus the expected work cycle be a guide in selecting the correct replacement. Also consider these factors: Match the engine’s performance and cost to your specific application to get the optimum performance at an affordable price. That means better value for you.

To find the correct replacement engine, find the type of drive shaft you need. Just follow the guide below:

Horizontal engines - have the drive shaft on one side.Vertical engines - have the drive shaft on the bottom.

Gas with a Horizontal Shaft

Gas with a Vertical Shaft

Diesel with a Horizontal Shaft

Diesel with a Vertical Shaft

Try to determine the horsepower of the engine you are replacing. If you do not know the horsepower exactly, that’s OK since most engines within a power range have a similar pattern for the bolts that mount the engine. For example, most 3 to 5 H.P. engines have the same bolt pattern.

Other features to look for:

Muffler Direction

Fuel Tank size

Starter - Electric/Rewind

Alternator Rating

Horizontal Crankshaft Engines
